Best AI search agencies for Swiss B2B companies

The ten at a glance

The four standards everyone here is judged on

AI search visibility is a young service, and most of the differences between agencies are invisible until you are three months into a contract. These four questions surface them early.

1. Do they measure real AI answers? The answers a buyer sees come from the consumer apps (chatgpt.com, Gemini, Google's AI Mode), which search the web live. A model's API answers differently. And because AI answers vary from run to run, a single run of a question tells you little. AirOps' 2026 State of AI Search found only 30% of brands stay visible from one answer to the next, and 20% across five consecutive runs.

2. Can you see the price before a call? Unpublished prices tend to move with how you answer the discovery questions.

3. Is there proof that is about AI search, not just SEO? Ranking on Google helps, but a case study about organic traffic does not show an agency can get you named in ChatGPT's shortlist.

4. How do they earn mentions on other websites? In Ahrefs' May 2025 study of 75,000 brands, branded web mentions correlated with AI Overview visibility at 0.664, against 0.218 for backlinks. Its December 2025 follow-up found YouTube mentions correlated most strongly of all, at about 0.74, across ChatGPT, AI Mode and AI Overviews. Off-site work is where AI visibility is won, so it is also where shortcuts get taken.

The column where REVEX reads worst is the fourth. It has no published case study yet: its first client engagements began in October 2026, and it will publish results when they are measured, not before.

1. REVEX

Best for: Swiss and European B2B companies that want AI visibility measured on real answers before they commit to a retainer.

REVEX asks a client's buyer questions on ChatGPT, Gemini and Google AI Mode the way a signed-out buyer sees them, and on Perplexity through its API, three times each, and stores every answer and every cited source. The work that follows is the part most dashboards leave to you: pages that answer the buyer questions directly, fixes that let AI crawlers read the site, and earned mentions on the sites each engine actually cites for that client.

Pros. Prices published before any call. Every number traceable to a stored answer. Free eight-question snapshot for qualified companies.

Cons. New in 2026, with no published case study. A small team, so a limited number of pilots at once. No German-language content team, which matters for most of the Swiss market.

2. Digital Leverage

Best for: larger Swiss brands that want a German-speaking LLMO partner with a long client list.

Digital Leverage is a Zurich agency with 13 years in search and content. Its LLMO offer runs from customer-journey workshops and a technical check to a strategy within four weeks, then implementation through founder and expert interviews, product-led content, link building and digital PR. It tracks prompts with Peec AI and reports in Looker Studio.

Pros. One of the few Swiss agencies to publish a price range, and an established client base.

Cons. The results on its LLMO page measure Google traffic, not AI answers. The monthly price after the audit is not published.

3. BlueGlass

Best for: organisations that want a strategy and roadmap first, with implementation optional.

BlueGlass, part of Team Farner in Zurich, sells GEO as four steps: discovery and goals, an audit of brand visibility across LLMs and AI Overviews, a prioritised roadmap, and optional help with implementation, including PR. It names eCommerce, healthcare, B2B, lobbying and public affairs as its fields.

Pros. A clear, low-commitment entry: you can buy the roadmap without the implementation.

Cons. No published price and no AI-specific result to judge it by.

4. Digital Creators

Best for: Swiss SMEs and shops that want a fixed monthly price.

Digital Creators, based at HSLU in Lucerne, sells “SEO für KI” as monthly packages covering technical SEO for bots, JSON-LD structured data, semantic content, prompt engineering and reporting.

Pros. The clearest published prices in Switzerland, at a level small companies can test.

Cons. Off-site mentions are not part of the listed offer, and that is where most AI visibility comes from. Built for SMEs rather than B2B companies selling internationally.

5. Worldsites

Best for: companies already working with Worldsites on ads or analytics.

Worldsites lists a GEO audit, strategy, content optimisation with statistics, quotes and structured data, technical work and monitoring. It cites 29 years of experience and work in 87 countries.

Pros. One agency for paid, analytics and GEO.

Cons. No price and no GEO result. The page quotes market statistics without naming their sources.

6. Sumasearch

Best for: a free first look at your GEO potential from a Swiss search agency.

Sumasearch's GEO offer covers content and entities, knowledge bases and references, technical GEO, off-page signals and mentions, and monitoring, starting with a free potential analysis.

Pros. Off-page mentions are explicitly part of the offer, and the first analysis is free.

Cons. No price, no AI-specific result, and the page has not changed since October 2025.

7. Radyant

Best for: funded DACH scale-ups and Mittelstand companies that want SEO, AI search and content in English and German.

Radyant is an organic growth agency covering SEO strategy, AI search (AEO/GEO), programmatic SEO, content, digital PR and CRO, written per market in up to four languages.

Pros. The strongest AI-specific case study among the DACH agencies here, a published price, and Swiss references.

Cons. The entry price puts it out of reach for most small companies. Not Swiss-based.

8. Discovered Labs

Best for: growth-stage B2B SaaS companies that want high content volume.

Discovered Labs publishes its full pricing: a €4,370 diagnostic credited to the first month if you sign within 14 days, then Establish at €6,995 a month (up to 20 content units and Reddit engagement at 10 mentions a month), Compete at €10,995 and custom work from €15,995. Retainers are month to month with 30 days' notice.

Pros. Fully published pricing, no lock-in, and a measurable AI-specific case study.

Cons. Its own blog says it runs Reddit engagement through “dedicated aged accounts”, which sits uneasily with Reddit's rules on undisclosed promotion; ask how it is done before you sign. Built for SaaS in English.

9. Omniscient Digital

Best for: large B2B software companies with a substantial annual budget.

Omniscient Digital is a US organic growth agency for B2B software covering SEO, AEO, content and digital PR.

Pros. Deep B2B software references and published AI-visibility results.

Cons. The price is an annual commitment at a level few Swiss companies would start with, and the focus is the US market.

10. OutreachBloom

Best for: buyers who want a rate card with deliverable counts.

OutreachBloom publishes two AI visibility tiers: $3,400 a month for 10 pillar pieces, 40 Reddit engagements and 10 earned citations, and $4,900 for 15, 60 and 15.

Pros. You know exactly what you buy each month.

Cons. Counts of pieces and engagements are outputs, not outcomes; ask how AI visibility is measured. Not focused on Europe.

What the rankings get wrong about price

Neither of the first two is a wild error, but both would change a budget. The fix takes two minutes: open the agency's own pricing page before you trust any figure, including the ones here.

What actually breaks, and why

Reporting without action. Tracking tools start at around $95 a month (Peec AI). A retainer earns its price only if someone changes what the engines read: your pages and, above all, what other sites say about you.

Measuring once. A single run of a question can show you in or out by chance. Without several runs and a set of questions you deliberately do not work on, nobody can tell whether the work moved anything.

Counting the wrong mentions. If your company shares a name with another one, a naive tracker counts their mentions as yours. Our own name, REVEX, is shared by a UK payments firm, a supplement and a software tool, and an unfiltered count put us at 8 of 24 answers when the real figure was 0.

Content without corroboration. Owned pages matter, but about 82% of AI citations come from earned media (Muck Rack). An agency that only writes blog posts is doing the smaller half of the job.

Five questions to ask before you sign

1. Which engines, which surfaces, how many runs? Consumer apps or APIs, and how many runs per question.
2. Can I see the answers, not just a score? You should be able to read any answer a report is built on.
3. Which questions will you not touch? A control set is how you tell results from noise.
4. How exactly do you earn mentions on other sites? Ask about Reddit accounts and review campaigns by name.
5. What does month four cost, and can I stop? Compare notice periods and minimum terms before features.
